BY/gm Patented Mar. 7, 1950 UNITED STATES FFECE 3 Claims.

This invention relates to improvements in key rings and has particular reference to a two piece ring type.

The princ pal object of the present invention is the provision of a segmental, arcuate, tubular member having an arcuate slide rod mounted therein and adustable to permit the removal of keys from the ring at either end of the tubular member.

Other objects are simplicity and economy of construction ease and convenience of operation, and adaptability for use in carrying the various types and sizes of keys.

With these ob ects in view. as well as other objects wh ch will appear during the course of the specification, reference will be had to the dra ing wherein:

Figure 1 is a side elevation of a key ring embodying this invention.

Fig. 2 is an edge view of the ring.

Fig. 3 is a sectional view taken on the maior plane of the ring with the ring opened at the right side.

Fi 4 is a view similar to that shown in Figure 3 with the ring opened at the left side.

Fig. 5 is an enlarged sectional view taken on line VV of Figure 1.

Fi 6 is an enlarged sectional view taken on lin VIVI of Figure 1.

Fi '7 is an en arged sectional view taken on line VII-VII of Figure 1.

Th o ghout the several views like reference characters refer to similar parts and the numeral Ill de i nates a se mental, annular tube of substant al y 300", open at its oppo ite ends l2 and I4. and p ovided at its central portions with spaced apart inde tures l6 forming sto'os l8 and 20 in t e c annel 22 f the tube Ill. The indentures it; are preferably made on the inside wall of tube ill, as s own, but will produce the desired stop re ardl ss of their position about the pe p erv of the tube section.

The other member of the ring comprises a semicircu ar r d 9.4 having ts axial diame er substantially eoual to t e ax al diameter of tube In. Rod 24 is of a gau e suitab e for a sliding fit in tube l0 and is substantially sem circular as shown, so that when it is in the position shown in Figure 1 it will overlap the end portions of tube Ill,

and will hug the walls of the tube sufficiently to prevent accidental movements of the parts. When the rod 24 is moved to the position shown in Figure 3, one end of 24 will contact the stop I8 to limit its inward movement when the slide and tube are opened at 26. By pushing the slide 24 in the reverse direction as shown in Figure 4 the opening will be at 28 and the other end of 24 will be against the stop 20. This double positioning of the slide rod 24 permits of better removal of the keys from the ring, due to the fact that they may be removed from openings formed at either end of the ring tube.

In order to more accurately position slide rod 2:? in the closed position, a notch 30 is formed in the outer surface of rod 2% adjacent its central portion so that the operator may determine the degree of insertion of the rod in the opposite ends of the tube.

When the slide rod is positioned as shown in Figures 3 and 4, it may be forced sideways so as to be removed from the tube, furthermore, it may be assembled in similar manner, and will normally maintain its operative position.

What I claim as new and desire to protect by Letters Patent is:

l. A key ring comprising a segmented annular tube member having open ends and provided adjacent its central portion with spaced apart internal stops, a single arcuate slide rod of shorter length than and mounted for sliding adjustment in said tube, and adapted to contact one of said stops with its other end disposed in spaced apart relation outside said tube to form a gap therebetween and adapted to be moved to completely close said segmented tube.

2. A key ring comprising an open arcuate tube member of substantially 300, stops extending into the channel of said tube adjacent its central portion, and an arcuate slide rod fitted into said tube to close said tube and to be moved so that its one end is positioned against one of the stops in said tube as its other end is positioned in spaced apart relation outside the other end of said tube to form a gap for the reception of keys.

3. A key ring comprising an open arcuate tube member of substantially 300, spaced apart stops extending into the channel of said tube adiacent its central portion. an arcuate slide rod of substant ally 180 fitted into said tube with its one end posi ioned against one of the stops in said tube as its other end is positioned in spaced apart relation outside the other end of said tube. and having a notch formed at its outer central portron.
